This project, the historical contribution to the development of high-energy laser technology can not be ignored, so that the level of laser technology in China on a higher level. The results: to build a large-diameter (120 mm) with the size of the project oscillation - amplification laser system, the maximum output energy of 320,000 joules; improve the beam quality up to 30000 joules. System technology integration, successfully targeting experiments, the indoor 10 meters at the breakdown of 80 mm aluminum target, outdoor 2 km from the breakdown of 0.2 mm aluminum rake, and a systematic study of the biological effects of intense laser radiation and material damage mechanism . First revealed the light on the laser system optical damage phenomena and mechanisms. green laser pointer could serve as the best pointers.
First in-depth understanding of the importance and physical meaning of the laser beam quality, using a series of innovative technologies that improve the beam quality, such as 000 joule level unstable resonator laser sheet laser oscillation - scanning the amplified laser system, a sharp cleaving method beam quality diagnostics. (5), laser components and support technology, a breakthrough was improved, such as low absorption of the high uniformity of neodymium glass melting process, the high-energy pulsed xenon dielectric film of high strength, large diameter (1.2 m) optical precision machining. (6) training and created a number of technical backbone team. High-power laser systems and nuclear fusion research 1964 Wang Ganchang independently by laser fusion Initiative project began in 1965. It is the product presentation of laser pointer .
After years of hard work, the completion of the output power of 10 (superscript 10) watts of nanosecond laser device, the first time in May 1973 and played in the low temperature solid deuterium target, at room temperature lithium deuteride target of deuterated polyethylene the child. 1974 successfully developed the first multi-way slab amplifiers, the laser output power increased by 10 times, an order of magnitude increase in neutron yield. Decrypted to the heart contraction principle in the international arena, actively track and six-beam laser system was developed in 1976, the inflatable glass bulb target irradiation, nearly a hundred times the body compression. A major breakthrough in this series of laser fusion research advanced in the world, but also laid the foundation for future long-term sustainable development. The portable green laser is convenient for use.
Military laser research in December .1966, the National Defense Science and Technology Commission chaired the military laser Planning, 48 units more than 130 people attended, the meeting formulated containing 15 kinds of laser machine, nine kinds of support supporting technology development plan. Although not formally approved to take effect, but still played a useful role in promoting. Within the next few years, this area has emerged in a number of important results. Such as: range laser from the technology first test: YAG Q-switched laser repetition rate of 20 Hz ranging accuracy of better than 2 m, as far as measuring the distance of 660 km, plus the theodolite on a single station can be realized on flying targets orbit determination. This outcome for the future to create the necessary conditions for the intercontinental missile re-entry trajectory measurements. Wavelength of the green ray usa green laser pointer is 532nm.
Ruby laser satellite ranging: U.S. experimental satellite Expl-27, 29 and 36 were measured, can be measured as far as the distance of 2300 km, an accuracy of 2 meters. This is the first generation of satellite ranging results for future long-distance and laid the foundation for more accurate satellite ranging. Ruby laser radar and airborne infrared laser radar, the first time the track ranging ground - empty and empty - empty aircraft. Aerial survey laser instrument: the laser rangefinder and aerial camera combination, by the aircraft airborne aerial complete the surveying and mapping of remote areas such as complex terrain. Repetition rate of 6 beats / min, ranging accuracy of 1 meter. Ground artillery laser rangefinder: can be independently observed, ranging, goniometer (direction and elevation angle) and needle orientation function. green laser pointer is the good choice for superior and fashionable business gifts.
